White House chief of staff William Daley quits

White House chief of staff William Daley has resigned and will be replaced by President Barack Obama's budget chief Jacob Lew, senior administration officials have said.

Obama is expected to make an announcement in this regard shortly.

Daley is now returning to Chicago, his home town.

"Daley gave his letter of resignation to the president in a private meeting in the Oval Office last week, recounting the administration's successes of his one year on the job and saying it was time for him to return to his hometown of Chicago," said The Chicago Tribune, which was the first one to break the news.
